如何使用JAXB的马歇尔/解组一的为myBean

Question

收集我有一个为myBean注释

@XmlRootElement 
public class MyBean ... 

编组/解组为myBean W/O问题，例如

JAXBContext jaxbCtx = JAXBContext.newInstance(MyBean.class); 
Marshaller m = jaxbCtx.createMarshaller(); 
m.marshal(myBean, writer); 

我该如何使用JAXB来编组/收集列表？

我尝试导致此错误：

javax.xml.bind.MarshalException 
- with linked exception: 
[com.sun.istack.internal.SAXException2: unable to marshal type "java.util.ArrayList" as an element because it is missing an @XmlRootElement annotation] 
    at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.write(MarshallerImpl.java:304) 
    at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.marshal(MarshallerImpl.java:230)

你必须创建MyBeanList类型的其他元素，并使用它。有关SO Using JAXB to unmarshal/marshal a List<String>
